Operating heterostructures against photovoltaic action

This work puts forward the theoretical observation that open circuit voltage (V oc ) loss at illuminated wide band gap side of a PN heterostructure is directly proportional to discontinuity heterostructure. photovoltage an effect photocarrier confinement and cannot be detected device terminals as separate measurable voltage. Wrongly illuminating heterojunction solar cell results in excess build-up charge carriers, thus, increasing electrostatic pressure cell.
